Hauptbahnhof, Zurich

Large station with the capacity to efficiently move a lot of passengers. Signs are uniform which makes navigation a breeze. Plenty of amenities (market, restaurants, etc.). Great place to start a trip, end a trip, or simply spend time. (I was an English-speaking tourist visiting the area and had no problems at this station.)

Largest railway station situated in Switzerland. They have nice connections by bus, boat and trams. You can also do some shopping in the basement where there are many stores present. It is like a city under a city. They also have cloak rooms and lockets to put your stuff. You can also get your currency changed at the station itself.
